PERPETUL CALENDA.

SPECIFMATION forming part of Letters Patent No. 604,649, dated May 24, 1898,. Application filed May 25, 1897. Serial No. 638,051. (No model.)

To (LZZ whom, it may concern:

Be it known that I, OCTAVIUS HENRY ST. GEORGE ANSON, of Madison, in the county of Dane and State of Wisconsin, have invented certain neu7 and useful Improvements in Perpetual Calendars; and I do hereby declare the following to be a" full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in calendars, and has for its object the production of a calendar of the perpetual type embodying the desirable advantages of cheapness and simplicity.

With this and other advantages in view the invention consists in the novel constructions and combinations hereinafter more fully described, and particularly pointed out in the appended claim.

In the accompanying drawings, illustrating the invention, Figure l is a perspective view of the calendar. Fig. 2 is a front elevation or face view of the same, showing the calendar-card removed; and Fig. 3 is a longitudinal sectional view `on the line 3 3 of Fig. 2.

Referring now more particularly to the drawings, the numeral l designates the calendar-frame, which is open at the front, as shown, to expose the calendar face or card 2. This case is provided With a pivot-ed back 3, designed to serve as a rest for supporting the calendar in an upright position.

The calendar card or face 2 is provided with columns of numerals representing days of the month in groups of seven, except the last column, which has only three numerals, the numerals of the several columns ranging from 1 to 31, inclusive. The calendarcard is also provided at one side adjoining the first column of numerals with a longitudinal slot 4 to expose an endless roll 5, containing the names or abbreviations of the days of the Week in their regular sequence or order. This roll is mounted upon shafts 5 6, having bearings in the end Wall of the frame, and the latter is provided on the exterior with a knob 6, whereby it may be revolved to move the roller. \The calendar face or card is also provided with slots 7 and 8 at the top thereof, the former beingemployed to expose a portion of a roll 9, which bears the names or abbreviations of the months of the year. This roll is mounted upon shafts 10 11, the former being provided with a knob 10f. The slot Sis arranged at one side of the said slot 7 and is designed to expose a roll 12, bearing terminal numerals 97 to 15,representing the fractional year or portion of a century. This roll is mounted upon shafts 13 14, the former provided with a knob 14% The face of the calendar-card on the opposite side of the slot 7 from the said slot 8 bears the numeral 19, and arranged above it is a perforated slip 15, bearing, the numeral 18. These numerals 18 and 19 are designed to be read in connection with the numerals on the roll 12 to designate the year. Thus the slip 15, bearing the numeral 18, will be employed in connection with the numerals 97, 98, and 99 on the roll 12 until the year 1900, when the said slip will be detached to vexpose the numeral 19, which is adapted to be employed in connection with the numerals OO up to l5 on said roll. It will be understood, of course, that the roll may be provided with numerals adapted to extend through an indefinite period.

'lhe columns of the numerals on the calendar face or card 2 range, as before stated, from 1 to 31, inclusive, which adapts it for use for indicating the days of the month, arranged in 28 the lowest or 31 the highest. I have provided a concealing-slide 17, adapted to conceal one or all of the numerals in the last column, so that the calendar face or card may be made to expose only the number of days contained in the calendar monththat is, twenty-eight for February, thirty for April, and thirty-one for May. This concealing-slide is constructed to correspond with the appearance of the face or calendar card and is connected with the shank of an actuatingslide 18, which projects through and operates in a longitudinal slot 19 in the frame adjoining one side thereof.

My invention provides a simple and inexpensive construction of calendar which may be adapted for use for an indefinite period. The desideratum in a calendar of this characier is cheapness and simplicity, and this my invention embodies.

Having thus described my invention, what IOS I claim as new, and desire to secure by Letters Patent, is

In a calendar of the character set forth, theA combination of. a rectangular frame openat the front and having a pivoted back to serve asa rest therefor, and also formed with a 1ongitudinal slot in one of the frame sides, a calendar-card mounted lin the said frame and' divided into columns representing the days of the month and also formed with a longitudinal slot as well as upper slots, Vanjendless roll movable against thelack of thel Aframe containing days of the week and also an upper roll .bearing the names of the months' ofl the year, one of the slots at the top-of the frame being adapted to expose a roll bearing terminal numerals representing the fraction of a year or portion of a century, and a concealing-slide movable over the card at one sidethereof to conceal one or all of the numerals in the last column of the same, and connected to cranks of an actuating-slide, the said 'cranks projecting through the slot in one 'side'of the frame and the actuating-slide being of greater width than the said slot and located on the exterior of the frame and provided'with an operating-knob,the said shanks kalso providing stops to abut against the upper and lower terminations of the slot in the side of tlie frame and limit the movement of vthe concealing-slide.
